Pediatric acute laryngitis is one of the emergencies in otolaryngology, commonly seen in infants and toddlers aged 6 months to 3 years. The onset of this disease is sudden, with rapid changes, and if not treated in time, it can be life-threatening. Therefore, it is crucial for parents to understand how to diagnose pediatric acute laryngitis. Below, experts from Chengdu Gospel Ear, Nose, and Throat Specialty Hospital introduce diagnostic methods for pediatric acute laryngitis.
I. Symptoms and Signs
The onset is relatively sudden, often accompanied by fever, hoarseness, and coughing. Initially, hoarseness is usually not severe, with wheezing during crying. As inflammation spreads to the subglottic area, it results in a hollow, barking-like cough, with symptoms worsening at night. In more severe cases, inspiratory stridor, inspiratory breathing difficulties, and signs of laryngeal obstruction such as inward suction of soft tissues in the supra-sternal fossa, supraclavicular fossa, intercostal spaces, and upper abdomen may appear. Severe cases may exhibit cyanosis or pallor around the mouth and nose, cyanosis of fingers and toes, restlessness, and sweating. If not treated promptly, the child may become pale, experience weak respiration, circulatory and respiratory failure, unconsciousness, convulsions, and even death.
II. Pathophysiology
It often occurs as a secondary condition to rhinitis, pharyngitis, and upper respiratory infections. It can also be a precursor to acute infectious diseases such as influenza, pneumonia, measles, chickenpox, whooping cough, scarlet fever, etc.
III. Diagnostic Tests
If a laryngoscopy is performed, laryngeal mucosal congestion and swelling, vocal cord congestion appearing red with dilated blood vessels, and attachment of purulent secretions on the glottis may be observed. Subglottic mucosal swelling protruding towards the middle forms a narrow cavity. Diagnosis is typically straightforward based on its characteristic symptoms such as hoarseness, laryngeal wheezing, barking-like cough, and inspiratory breathing difficulties. A laryngoscopy may be necessary when required.
Treatment Link: American Jesse Low-Temperature Plasma Ablation Treatment System Specifically for Pediatric Laryngitis
The American Jesse Low-Temperature Plasma Ablation Treatment System mainly uses an electrode to emit plasma high-frequency ion current, causing the diseased tissue to heat up to 45-70°C, leading to water vapor evaporation, protein denaturation and necrosis, and effectively killing diseased tissue cells quickly. This causes surrounding blood vessels to constrict, seal off, and coagulate. It helps preserve the physiological functions of the nasal cavity and throat.
This therapy has been recognized by the World Health Organization as the best method currently available for treating chronic nasal and throat diseases. Additionally, this treatment method causes minimal damage to the throat, making it especially suitable for weak children.
